4. Systematic Study: Many students have the bad habit of jumping directly into the exercises without first reading the theoretical portion of the chapter from the NCERT. You won't be able to understand the subject unless you study the theory. If you wish to answer all of the questions properly, make it a habit to first study the topics before moving on to the back exercises.

5. Simplify your Preparation: Divide the whole curriculum into tough, moderately difficult, and easy sections. Simplify your preparation as much as possible by further subdividing a chapter.

9. Make a Conscious Effort to Create a Learning Environment Around You: The environment you create before your final exams will be critical in your Science test preparation. As a class 7 student, you must endeavour to create a comfortable, quiet, and distraction-free environment for yourself.

10. Don't Emulate Toppers, Prepare your Own Unique Strategy: If you are a morning person, try to prepare your difficult section of the syllabus before noon, and if you are a night person, schedule your study hours appropriately. Study during a time when you are most productive and least prone to distractions, based on your own abilities and weaknesses.

11. Make the Most of Every Opportunity: When preparing for Science NCERT Class 7 examination, attempt to incorporate short breaks into your schedule.

14. Study Wisely: If you've already learned a concept, you should devote more time to strengthening your weaker portions in the Science syllabus. By analysing past year papers, you must carefully analyze what kind of questions are most likely to be asked in the Science exam. First, finish the most significant topics from an examination standpoint before moving on to the least important ones.

15. Clear any Doubts as Soon as Possible: Another important piece of advice while studying for the Class 7 Science examination is to seek immediate clarification from your instructor on any topics that you haven't understood.
